Definitions

  • the present invention relates to a method of combating insects and acarids, insecticidal and acaricidal compositions and their preparation.
  • the invention provides a method of combating insects or acarids at a locus infested or liable to be infested with them, which method comprises applying to the locus:
  • the invention provides an insecticidal or acaracidal composition
  • compositions are unexpectedly advantageous.
  • Components (A) and (B) are synergistic, being surprisingly effective.
  • the method and composition achieve a greater insecticidal or acaricidal effect, e.g. against insects or acarids which attack crops above ground, then the additive effect of the essential components. They are particularly useful against insect and acarid pests of crops.
  • the proportions of (A) to (B) can vary over a wide range depending on such factors as the particular locus to be treated, the particular pests to be combatted and the particular effect desired. Overall, however, the proportions of (A) to (B) may be for example from 1:20 to 5:1 respectively. There may be a greater weight of (B) than of (A), or a greater weight of (A) than of (B). Generally the proportions of (A) to (B) are from 5:1 to 1:2.5, preferably from 3:1 to 1:2, especially from 2:1 to 1:2, respectively. In a preferred embodiment, the proportions of (A) to (B) are 1:1-2.5 respectively. Parts, proportions and percentages in this specification are by weight unless otherwise indicated.
  • Component (B) is preferably one or more, preferably one, of aldicarb (2-methyl-2-(methylthio)propionaldehyde O-methylcarbamoyloxime), carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate), terbufos (S-tert-butylthiomethyl O,O-diethyl phosphorodithioate), phorate (O,O-diethyl S-ethylthiomethyl phosphorodithioate), disulfoton (O,O-diethyl S-2-ethylthioethyl phosphorodithioate), dimethoate (O,O-dimethyl S-methylcarbamoylmethyl phosphorodithioate), 3,3-dimethyl-1-methylthio-2-butanone O-methylcarbamoyloxime, acephate (O,S-dimethyl acetylphosphoram
  • (B) is 3,3-dimethyl-1-methylthio-2-butanone O-methylcarbamoyloxime.
  • the essential components (A) and (B) can be applied together in a composition comprising (A) and (B).
  • the compositions can be prepared by admixing the ingredients.
  • the compositions may initially be produced in the form of concentrates, e.g. containing 0.5-85% in toto of the essential components (A) and (B), and these may be diluted with water or a hydrocarbon, usually water, at the point of use for application by spraying, generally such that the concentration in toto of (A) and (B) is 0.02-3%, e.g. 0.1-3%, preferably 0.15-2%.
  • the compositions are produced directly for application, e.g. in the form of dusts or granules.
  • a preferred composition is in the form of granules containing 1.5-3% (A) and 3-5% (B), e.g. 1.5% (A) and 3.5% (B).
  • compositions may contain for example 0.02-85% in toto of (A) and (B).
  • compositions normally contain a carrier and/or a surface active agent.
  • the carrier may be a liquid, e.g. water (e.g. water used to dilute a concentrate for application).
  • An organic solvent may be present with the water though this is not usually employed.
  • the carrier may be a liquid other than water, for example an organic solvent, e.g. a water-immiscible solvent, for instance a hydrocarbon which boils within the range 130°-270° C., in which the essential components are dissolved or suspended.
  • a concentrate containing an organic solvent may contain a surface active agent so that the concentrate acts as a self-emulsifiable concentrate on admixture with water.
  • the carrier may be a solid, which may be finely divided.
  • suitable solids are limestone, clays, sand, mica, chalk, attapulgite, diatomite, perlite, sepiolite, silicas, silicates, lignosulphonates and solid fertilizers.
  • the carrier can be of natural or synthetic origin or can be a modified natural material.
  • Wettable powders soluble or dispersible in water may be formed by admixing the essential components with or without a carrier with a surface active agent.
  • the essential components are admixed with a solid carrier to form a dust, powder or granular product.
  • ⁇ surface active agent ⁇ is used in the broad sense to include materials variously called emulsifying agents, dispersing agents and wetting agents. Such agents are well known in the insecticide and acaricide art.
  • the surface active agents used may comprise anionic surface active agents, for example soaps, fatty sulphate esters such as dodecyl sodium sulphate, octadecyl sodium sulphate and cetyl sodium sulphate, fatty aromatic sulphonates such as alkyl-benzene sulphonates or butyl-naphthalene sulphonates, more complex fatty sulphonates such as the amide condensation product of oleic acid and N-methyl taurine or the sodium sulphonate of dioctyl succinate.

  • the surface active agents may also comprise non-ionic agents, for example condensation products of fatty acids, fatty alcohols or fatty substituted phenols with ethylene oxide, or fatty esters and ethers of sugars or polyhydric alcohols, or the products obtained from the latter by condensation with ethylene oxide, or the products known as block copolymers of ethylene oxide and propylene oxide.
  • non-ionic agents for example condensation products of fatty acids, fatty alcohols or fatty substituted phenols with ethylene oxide, or fatty esters and ethers of sugars or polyhydric alcohols, or the products obtained from the latter by condensation with ethylene oxide, or the products known as block copolymers of ethylene oxide and propylene oxide.
  • the surface active agents may also comprise cationic agents, for example cetyl trimethylammonium bromide.
  • Preferred surface active agents include fatty alkyl sulphates, alkyl aryl sulphonates, fatty alkyl ethoxylates, sulphated fatty alkyl ethoxylates, dialkyl sulphosuccinate esters, the amide condensation product of oleic acid and N-methyl taurine, lignin sulphonate salts, sulphonated naphthalene-formaldehyde condensates and sulphonated urea-formaldehyde condensates.
  • compositions can contain a coating of an adhesive agent, e.g. a cellulose ether, and this can prolong the residual activity by forming a coating, thus inhibiting the physical removal of the active ingredients e.g. by wind, rain or rubbing.
  • an adhesive agent e.g. a cellulose ether
  • compositions such as is discussed above, they can be applied separately in analogous compositions containing just (A) or (B), particularly as whole or part of a chemical insect or acarid control programme in a crop season.
  • (A) is applied at or immediately before planting a crop and (B) is applied after emergence of the crop.
  • Both simultaneous and sequential application may be employed, e.g. a mixture of (A) and (B) applied at or immediately before planting a crop and (B) applied after emergence of the crop.
  • (A) and (B) may be mixed immediately before use. Desirably, however, they would already have been mixed.
  • the invention provides a one pack presentation, in which (A) and (B) are already mixed, and also a single package designed to hold (A) and (B), e.g. in the form of compositions such as are discussed above, in separate containers, for mixing of (A) and (B), e.g. in a spray tank, for application.
  • a further pesticide can be used in sequence or admixture with component (A) or (B).
  • (A) and (B) can be applied separately and a further pesticides applied with (A).
  • a composition comprising a mixture of (A), (B) and the further pesticide can be applied.
  • the proportions of (A) to the further pesticide are from 1:10 to 20:1 e.g. from 1:10 to 10:1.
  • the further pesticide can be a further insecticide or acaricide. It can also be a molluscicide, e.g. methiocarb (3,5-dimethyl-4-methylthiophenyl methylcarbamate) or metaldehyde, or a nematicide, e.g.
  • fenamiphos ethyl 3-methyl-4-(methylthio)phenyl 1-methylethylphosphoramidate
  • aldicarb (2-methyl-2-(methylthio)propylideneamino methylcarbamate) or oxamyl (S-methyl-N',N'-dimethyl-N-(methylcarbamoyloxy)-1-thio-oximidate).
